What is Semi-Quantitative Elemental Determination?

Semi-quantitative elemental determination is the process of identifying and measuring approximate amounts of elements in a material. This method usually presents the concentrations of elements in a sample as ratios or estimated amounts rather than exact values. This type of analysis is used to obtain a rapid overall elemental profile and is particularly preferred in applications such as initial screening, quality control and process monitoring.

What is the XRF (X-Ray Fluorescence) Method?

XRF is a non-contact analysis method that uses X-rays to analyze the atomic structure of elements in a sample.

How Does It Work?

• When X-rays hit a sample, the atoms in the sample emit fluorescence (secondary X-rays).
• This emission reveals a “fingerprint” like spectrum where each element has a unique energy level.
• This spectrum provides qualitative (which elements are present) and semi-quantitative (approximately how much of the elements are present) analysis of the elements in the sample.

Benefits of XRF Analysis

1. Fast and Efficient Analysis: XRF determines the elemental composition of a sample in a very short time (usually within seconds or minutes). This is particularly advantageous for industries that require process monitoring and fast decision-making.
2. Non-Contact and Non-Destructive Measurement: The XRF method does not damage the sample. This makes it possible to analyze valuable, rare or unique samples.
3. Wide Element Range: With XRF, most of the elements in the periodic table can be analyzed. It is especially ideal for elements between sodium (Na) and uranium (U).
4. Application in Various Materials: It can analyze many different types of samples, including solids, liquids, powders and coatings.
5. Low Cost Operation: Although many samples can be analyzed, it is a low-cost method. Calibration requirements are minimal and consumables consumption is low.
6. Environmental Safety: No chemical reagents are required, reducing environmental risks and providing a safer working environment.
7. Mobile and Portable Solutions: Portable XRF instruments make it easier to analyze in the field. This is especially critical for applications such as mineral exploration, scrap metal separation and environmental monitoring.
